With reorder header off, received packets are untagged in skb_vlan_untag() called from within __netif_receive_skb_core(), and later the tag will be inserted back in vlan_do_receive(). This caused out of order vlan headers when we create a vlan device on top of another vlan device, because vlan_do_receive() inserts a tag as the outermost vlan tag. E.g. the outer tag is first removed in skb_vlan_untag() and inserted back in vlan_do_receive(), then the inner tag is next removed and inserted back as the outermost tag. This patch fixes the behaviour by inserting the inner tag at the right position. Signed-off-by: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp> Signed-off-by: David S. Miller <davem@davemloft.net>
